WASTE AND VERFLOW FIXTURE FR IBATHTUBS.

Application led September 19, 1925. lSerial No. 57,385.

To all whom 'it may concern:

Be it known that I, SAMUEL GADE, a citizen of the United States, and a resident of New York, in the county of New York and les State of New York, have invented certain new and` useful Improvements in Waste and Overflow Fixtures for Bathtubs, of which the following is a specification.

This invention relates to connected waste and overflow fixtures for bath tubs of the type which are concealed behind the wall of the tub and customarily located within the wall ofV masonry work adjacent thereto;

It is one of the objects of the invention to provide for the withdrawal of the waste valve andits operating members through, respectively, the waste opening and the overflow opening of the fixture, without necessitating the' breaking open of the wall adjacent the tub and dismembering the fixture to insert the same.

Another object`is to provide for a construction at the overfiow end 'of the fixture wherein'the operating handle and the valve operating .mechanism may be withdrawn for purposes of .adjustment or replacement without breaking the joint between the overiiow pipe and the tub.

A still further object is to make a fixture of this type self-draining, eliminating the accumulation of sediment and other foreign matter.

Still Iother objects will become apparent in the follwing specification and the accompanying drawings, in which- Fig. l is a Vertical longitudinal sectional view through the lixture, vwith the. waste valve inan open or draining position;

Like numbers ofreference denote similar parts throughout the several views and the ollowing specification.

10 is a bath tub which is of the usual construction and has an upwardly extending wall`11. 12 is an opening through the wall 1l of the tub near its top. At the rear of wall 11 is an elbow 13 having a lip 14 extending into the opening 12, an ,annular flange 14 surrounding the lip and fitting tightly against the rear side of wall 11. 15 is a ring disposed around opening 12 at the front side of the wall l1', provided` with inwardly projecting lugs 16 and 17. 18 and 18a are screws which, passing through holes in lugs 16 and 17, are screwed into lugs 19 and 19l at the inside of elbow 13, thereby securely fastening the elbow to theI wall l1 around the opening 12.

20 is an overflow pipe secured vertically at its' upper end to the elbow 13 and at its lower end to a T 21. 22 is an elbow fastened to the underside of the bottom of the tub 10 by means of a sleeve 23, in threaded engagement with elbow 22 at 24. The top of sleeve 23 is bored out interiorly at 25 and its bottom is somewhat smaller at 26, constituting a drain passage. 27 is a tapered seat for a valve 28 slidably disposed within the bore 26. Valve 28 has a head 29 provided with bottom, and arms 37 forming a slot 38 between them. Arms 37 are slotted obliquely at one side only at 39.

' 47 is'an overflow shield, substantially cupshaped, having its sides 48 lit? over the ring 15 against the wall 11 of the tub 10. At the lower half of ts'face, overflow shield 47 has slots 49, and its lower side has recesses 50 and'l. Y Between these recesses is a somewhat thickened portion forming a lug 52 which fits intoI a recess 15n at the bottom of the ring 15for the purpose of keeping the recessesof the shield in evenly spaced relation to the wall ofthe tub. 'Overflow shield 47 is securely fastened to the inside of elbow 13 by means of screws 53 and 54 which are in threaded engagement with lugs 19 and 19a. Above the slots 49, shield 47 has an inwardly .extending tubular extension 55, 56 is an operating lever h aving a handle 57 extending into the tub and a rod 58 into the elbow 13. 59 is a. ball-shaped portion at the center ofthe lever 56 being held in fluid' tight contact with shield 47 bymeans of a nut 60 at one side and a spring 61 at its other side, forming, the usual ball joint known as such in the art.

. Suspended from the extreme end of rod 58 of lever 56 is avturn buckle 62 which consists of a sleeve portion 63 having at one end a ybore 64a through which the rod 58 is passed which is provided with suitable pins 64 and 65 to prevent accidental loss of the turn buckle, and a link 66 in threaded engagemert with the other end of the turn buckle. A lock nut 67 is'provided to secure the link 66 to the turn buckle 62 in any desired adjusted position. 68 is -a .chain (shown diagrammatically only by a dotted line) connectingthe link 66 with the downwardly extending lug 43. of the eccentric disc 40 within the elbow, to which it is fastened by being passed through its bore 44. The

'chain 68 is led past aroller 69 rotatably mounted upon a shaft v within the 'l' 21, about in line with the top of the horizontal drain pipe 45. i

The operation of the waste and overflow fixture embodying the principles ofmy k,invention, is as follows: A Elbow 13 is secured to the opening 12 of the tub by means of ring 15, screws 18 and 18a engaging the elbow, as shown in Fig. 6, The elbow 22 with bracket 35, preferably, fastened therein, is connected to the undervtothe right lengths and placed in position with T 21 which latter is connected to the outlet pipe 46'. All this is done before the masonry worker walls of the bath room are completed, which can then be finished. In this manner, all bath tubs in an apartment house may be set up with their piping and all masonry work finished. y

In order now to complete the installation, l take the overflow shield 47 with its lever 56 and turn buckle 62 fastened thereto with chain 68 and eccentric disc 4() and screw it, around the ring 15, to the elbow 13 by means of screws 53 and 54, letting the disc 40 and chain 68 drop down through the elbow and pipe 2O to extendv somewhat into the pipe 46. I then insert a suitably bent hook made of wire through sleeve 23 and pipe 45 until I catch the downwardly hanging chain 68 and draw it with the eccentric disc 40 through pipe 45 into the elbow 22, where I slip the shaft 42 of the disc into the obliquely disposed slots 39 of the bracket 35', with the major portion of the eccentric disc proecting upwardly, as shown in Fig. 1. The valve 28 is then placed within sleeve 23 and the strainer plate 31 fastened over it. lith the various parts assembled, as shown inFigl, it is clearly evident that any water in the tub will be dischargedA through the strainer 31, sleeve 23, valve opening 26, elbow 22, pipe 45, into the outlet pipe 46. By giving the handle 57 of the lever 56 an upward position, the chain 68 will. loosen its tension on eccentric disc 40 and permit by gravity the same to assume the position indicated in F ig. 2 where owing to the eccentricity of the disc 40, the valve 28 is allowed to come to its seat'27 within the sleeve'23, thereby closing the water passage. Water will then fill the tub, until the supply is cut off or until its level reaches theoverflow slots 49 and recesses 50 and 51 in the overflow shield, when it overflows through elbow 13 and pipe 20 into outlet pipe 46.

- The lift of the valve 28 can be regulated by adjusting the set screw 32 and nut 34. Tightncss of the chain 68 and its proper tension on the eccentric disc is insured by adjustment between the turn buckle 62 and link 66. The roller 69 serves the purpose of eliminating unnecessary friction between the pipes and the chainl 68.

l/Vhen it is desired to readjust the tension of the chain, or to take the'wo'rking parts of the fixture out for inspection or repair, it is noty necessary, as in the usual constructions heretofore provided, to break the conllU and eccentric disc, the latter having previously been lifted out of bracket 35 manually through the waste opening.

It is clearly obvious that the assemblage and removal of the entire valve mechanism can be effected without disturbing the masonry work in the bath room, or the connections of the various pipes with each other or the tub. Furthermore, the valve 28 being located in the highest point of the waste passage below the tub, results in the absence of water trapped in the waste pipe which therefore are self-draining, preventing accumulation of sediment or other foreign matter. f

While AI have shown and described a pre-- ferred embodiment of my invention, I do not wish to limit myself' to the particular construction disclosed. It is obvious that various changes of form,y proportion, minor details and combination of parts may be rsortedto without departingr or sacrificing any of the advantages of the invention, as defined in the appended claims.
